WebbThe "triple junction" is an important part of the global plate movement system. The expanding Chilean ridge subducted into the South American plate to form the Chile triple junction and caused drastic topographical changes within a few hundred kilometers in the south of the Chile triple junction. The differences in factors such as the initial angle of … WebbWhen magma rises to Earth’s surface through fissures and volcanic vents, it is called lava. Lava cools and crystallizes quickly, so that igneous rocks formed from lava tend to consist of tiny mineral grains. (Sometimes cooling can be so rapid that mineral grains cannot form and a glass results.)
